Subject: carborattor oil...where does it go?
Hi,
I have 2 thought questions for you experienced souls.
1. What does the carborator oil do and where does it go so I have to refill
every 50 miles or so?
2. I understand mechanics and replacing static parts, but I want to learn
to do my own tune-up. Any suggestions as to where I might learn what a
tune-up does for an engine and how to do it? I guess I am asking for the
Roseta stone of car repair manuals. Titles???
TIA,
Bill, '76B<<
The purpose of the oil is to delay the rise of the piston when you accelerate,
so that the air fuel mixture is temporarily made richer. It performs a function
similar to the accelerator pump in U.S. carburetors.
If you are using the original Z-S single carburetor, you need to replace the
o-ring at the bottom of the piston. Look at a diagram of the cross section of
the carburetor in the Moss or VB parts catalog (sorry I don't have a page
reference
here at work). There is a screw at the bottom of the oil reservoir which holds
and adjusts the height of the needle. The o-ring seals the opening through
which
this screw passes. The screw is held captive by a star-shaped washer which
grips
the sides of the oil reservoir. To replace the screw, you need to get in there
with something to flip the star-shaped washer out of the way. Then remove the
screw, replace the o-ring, and put everything back together.
Alternatively, replace your Z-S with dual SUs and get back all the power which
your B is supposed to have.
